2) max. width 50.8mm
3) no fluid may leak out, no grease, oil or braid juice may pollute the track, no tire glue or similar
4) teams may ask for a special voltage where the car should be run.
the standard racing voltage depends on the motor. I will run all car @ 12V, SCX and Carrera motors @14V, G9330 motors @ 10V. Again, if i get another information, i will run the car at the desired voltage.
5) car must have a body that looks like a car
6) no silicone tires, rubber and PU are fine,

concours de elegance: the best looking car will be voted by a poll open for all forum members

so i think these rules are wide open, so ladies and gentleman, i call you all out there to build your fastest, smoothest 1/43rd car for this race.
send in your trucks from the truck proxy we already had, just tune your stock SCX car a little and maybe blow the doors off all others, built something that was not seen before, it´s up to you.
Who will have the fastest car?
Small tip: K&D tires, Ortmann or JelClaws are the ones which work really good, foam tires don´t have grip on the flat latex surface.

The prices:
the first pick will go to the concours winner, than to the winner of the race, 2nd place concours, 2nd place race and so on...

list of prizes by now:
#1 Carrera Go! Porsche Spyder
#2 1/43rd 3D printed chassis for boxer (H0) Motor

list to be continued ....

have fun, Peter

Lloyd, great news, i´m looking forward to your entry!

Jaak, here´s a link to pictures from the track:

here are 2 pics:

what do you mean with posters, box stickers, etc?
"slowest 5 will be deleted" the race will run for 30 laps, the 5 slowest laps will be deleted out of the ranking and the remaining 25laps will used to calculate the average lap time. Reason for deleting: in this way i got 5 possible deslots and i can push the cars to their limits. or near the limit.

great news, Roland!

i´m already getting excited about the race

the list of prizes is growing:

list of prizes by now:
#1 Carrera Go! Porsche Spyder
#2 1/43rd 3D printed chassis including Fyrebox-1 motor donated by SlotCarExpress
#3 $20 gift certificate from ASCW (donated by Tsooko)
#4 $20 gift certificate from ASCW (donated by Tsooko)

thanks to Ted and Kihm!

and another prize:

#5 Carrera Ferrari 458 GTE donated by AmericanSlotCarWorld!

also, there is typing mistake in the header - it should read 78ft of track length (24m) not 38 ...
What i forgot in the first thread:
rule #7: ootb cars and ready (store bought) bodies (like Kyosho, Fastlane, etc) are excluded from the concours de elegance. Of course they will participate in the concours when you have done a paint/decal job.

So, the chassis is not only the chassis, there are also 4 pcs printed wheels in the size of SCX DTM wheels, along with SCX tires for the front and JelClaws for the rear. Guide, axles and guide wires, too. So, that makes it a full rolling chassis.
Another addition to the prize pool is one school bus, still mint :b

Hi Jaak,
i would go for the following:
motor: FyreBox-1 (Boxer)
if you want plastic gears, use 7/25
if you want brass/aluminium gears, go with 8/28
axle diameter 0.085"
.350"x.187"x.085" Double Flange Wheel for front wheels
.350"x.312"x.085" Double Flange Wheel for rear wheels
including Slicks (as Steve which one fit those wheels!)
you could also go with independent front wheels kit, would be a great choice.

I´ll PM you my adress!

great news, Jaak!
no need to pick numbers for this race.
Ted, the motor is my printed chassis car, the MCA Centenaire, is a stock mabuchi motor, with less than 20k rpms. Kihms motor, the FyreBox-1 has a much higher rpm rating. I have to push the voltage up to 15V to get straight line speed out of the mabuchi, while i have to throttle the voltage to 8V for the FyreBox-1 motor. Anyway, the size of the motors is the same, also the way how they distribute their power - under totally different voltage ratings.

Also on my track, the DSlot 962 is faster than the 917. Seems the longer guide length and weight distribution helps the 962. Stock DSlot motors work with stock DSlot gearing very well on my track @14V. With a good prepared DSlot, times near your best time could be possible.

Chuck carries K&D tires for the DSlots which are working simply awesome on my flat latex track. Most important point, as usual, is to get the tires very well trued.

Masmojo, looking forward to what you will come up with this time! Will you tune one of your former entries, too?

I will have to decide which car will run this race, hm..., the MCA again - orange or the red one, GT40 or 917. I think the 917 will get a chance to blow Ted´s doors off that McLaren, showing the those light weighted chassis can work well, too, on my track

i got no aftermarket tires for the DSlot lying in my boxes. The only tires are wide artin rears, SCX DTM Porsche Nascar wheels and some Ortmann slicks that will fit the 3D printed rims (same size as SlotDevil Micro Chassis rims). But they will not fit the DSlots

i could offer you 2 rims with slicks - axle diameter .085", but they have to be glued to the axles. These wheels are on my yellow GT40.

Jaak, for better tires contact Chuck from AmericanSlotCarWorld. He should have those K&D tires in stock. for sure with reasonable shipping costs, too.
btw. Steve surfaced in another forum yesterday.
awesome chassis construction, Marc!
i´m already looking forward how this one will run!
great work on the side panels.
no problem with slow, Mas!
Just wish the voltage up to 15V and it will run nice! I´m running all my SCX motors at 14 to 15V without any problems. They can stand this easily.
Nice car!
just some night racing impressions from the Desmo ...
trying to get some training laps done after difficult conditions

coming along great Marc!
The rear details are nice!
Another prize reached the ProNoMag racing headquaters:

Ted donated a $20 gift certificate from Ranch-Design to the prize pool!


#6 $20 gift certificate from Ranch-Design (donated by Tsooko)
yep, Ted´s at work

and so am i :evilgrin:

if it´s too fast, i´ll turn the voltage down ;p
Jaak, i can tell you that you improved over a stock Dslot!

what works in 1/43rd?
aftermarket PU tires
Tire glueing to the rims
Tire trueing and another time of tire trueing
Removing any unneccesary play where you can find it - especially in the rear axle.
Front tires that touch the track and carry a little weight.
trued/glued/sealed front tires
a rotating guide
high flexible silicone wires for the guide (the stock Dslot cable are POS)
a low center of gravity

did i forget anything?
(making list in mind: motors - no, not necessary can adjusted with voltage), gears - hm maybe, when they are smoother than the original, a deep sitting guide blade)
i don´t think so.

carefull tuning is the most important point IMO.

have a great evening,
